Tests at Microsoft's Linux lab show that counting the raw number of security updates required by the various operating system flavors is not as meaningful as examining the efficiency of the update process.

It is because they can just take apart the Linux source code and tell use that there method is better. We have to take what Microsoft say about there own OS because it's not opensource. They have captured Linux and are experimenting in there lab to find weaknesses and report it, they seem to be learning at the same time. Can anyone see what is happening here?
